      "value": "MWDB Core versions >=2.0.0 and <2.19.0 contain a missing authorization vulnerability in the deprecated config and blob upload endpoints. These endpoints accept the undocumented POST method, which bypasses the capability checks applied to the documented PUT method. This allows any authenticated user without the adding_configs or adding_blobs capabilities to upload config and text blob objects to the system. The impact is limited to adding new config and blob objects. This issue has been fixed in version 2.19.0"

      "value": "Las versiones de MWDB Core >=2.0.0 y anterior a 2.19.0 contienen una vulnerabilidad de autorización faltante en los endpoints de carga de configuración y blobs obsoletos. Estos endpoints aceptan el método POST no documentado, lo que omite las comprobaciones de capacidad aplicadas al método PUT documentado. Esto permite a cualquier usuario autenticado sin las capacidades adding_configs o adding_blobs cargar objetos de configuración y blobs de texto al sistema. El impacto se limita a añadir nuevos objetos de configuración y blobs. Este problema ha sido solucionado en la versión 2.19.0."
